Entera Bio Reports Phase 1 Clinical Data of First-in-Class, Oral PTH(1-34) Peptide Candidate (EB612) for Patients with Hypoparathyroidism at ENDO 2024

JERUSALEM, June 03, 2024 (GLOBE NEWSWIRE) -- Entera Bio Ltd. (NASDAQ: ENTX), (“Entera” or the “Company”) a leader in the development of orally delivered peptides and small therapeutic proteins, today announced Phase 1 clinical data for its hypoparathyroidism focused investigational program, EB612, as presented on June 1^st at the Endocrine Society ENDO 2024 Annual Meeting.

Entera’s EB612 program aims to provide the first oral PTH daily tablet hormone replacement therapy for patients suffering from hypoparathyroidism. Late stage investigational PTH replacement treatments include TransCon PTH (palopegteriparatide) by Ascendis Pharma A/S and eneboparatide (AZP-3601) by Amolyt Pharma. Both these modalities require patients to administer injections every day. Entera previously published positive Phase 2a study results in hypoparathyroid patients with four times a day (QID) regimen (Ish-Shalom, JBMR 2021) of EB612.

The data reported from this Phase 1 clinical study include pharmacokinetic (PK), pharmacodynamic (PD) and safety results from the application of a new generation of Entera’s N-Tab™ technology platform and EB612, the active peptide fragment 1-34 of the N-terminal region of human parathyroid hormone (teriparatide) dosed twice a day (BID).

Significant systemic exposure was reported following both administrations of EB612 tablets. Aside from positive PK measures, sustainable PD effects were reported, including serum levels of calcium (albumin corrected), phosphate, and 1,25(OH)₂-Vitamin D (reaching +3.9%, -20.8%, and +73.2% change on average from baseline, respectively) and decreased endogenous serum PTH(1-84) (reaching -43.0% change on average from baseline). There were no treatment-emergent Adverse Events of hypercalcemia reported. There were no treatment-emergent Serious AEs. The only Study Drug-Related AE was mild headache, reported in two out of fifteen subjects. No significant findings were observed in blood and urine lab tests. All vital signs were within the normal range.

“The encouraging findings from this Phase 1 study reaffirm the ability of our N-Tab™ platform to develop simple oral tablet treatments of important peptide therapeutics. Here we suggest that a BID administration of our unmodified PTH(1-34) peptide may provide a viable alternative for patients with hypoparathyroidism who require a peptide replacement therapy for life and are intolerant, adverse or cannot access a daily injectable product,” said Miranda Toledano, Chief Executive Officer at Entera.

About Entera Bio

Entera is a clinical stage company focused on developing oral peptide or protein replacement therapies for significant unmet medical needs where an oral tablet form holds the potential to transform the standard of care. The Company leverages on a disruptive and proprietary technology platform (N-Tab™) and its pipeline includes five differentiated, first-in-class oral peptide programs, expected to enter the clinic (Phase 1 to Phase 3) by 2025. The Company’s most advanced product candidate, EB613 (oral PTH (1-34)), is being developed as the first oral, osteoanabolic (bone building) once-daily tablet treatment for post-menopausal women with low BMD and high-risk osteoporosis, with no prior fracture. A placebo controlled, dose ranging Phase 2 study of EB613 tablets (n= 161) met primary (PD/bone turnover biomarker) and secondary endpoints (BMD). Entera is preparing to initiate a Phase 3 registrational study for EB613 pursuant to the FDA’s qualification of a quantitative BMD endpoint which is expected to occur by January 2025. The EB612 program is being developed as the first oral PTH(1-34) tablet peptide replacement therapy for hypoparathyroidism. Entera is also developing the first oral oxyntomodulin, a dual targeted GLP1/glucagon peptide, in tablet form for the treatment of obesity; and first oral GLP-2 peptide tablet as an injection-free alternative for patients suffering from rare malabsorption conditions such as short bowel syndrome in collaboration with OPKO Health.
